We can fix this read-only access issue primarily in two ways: MacOS doesn’t have native write support for NTFS, which means, you can only view or open files stored on the drive, but can’t edit, copy, move, or delete them. Have you ever come across the situation where your Mac just won’t let you write to an external drive? Most of the time, this might be because the drive you’re trying to save data to, is formatted as NTFS.
